Title: Process for the polymerization of olefines
IPC: C08F2/00
Filed: 1956-11-05
Abstract: Olefines are polymerized by use of a catalyst comprising a salt of a Group IVa, Va or VIa metal and an organo-metallic compound of an alkali, an alkaline earth or an earth metal or of zinc, in the presence of a diluent and wherein the reaction mixture continuously circulates from the reaction zone to a heat exchange zone and then back to the reaction zone and characterized in that the current of mixture outside the reaction zone is maintained in a state of laminar flow.  In the example the polymerization ingredients are ethylene, a hydrogenated hydrocarbon fraction, titanium trichloride and aluminium ethyl sesquichloride and the reaction is carried out in a specified continuous flow reactor. Two reaction zones may be used if completion of the polymerization is desired.  Specifications 799,392 799,823 and 801,031 also are referred to.

Title: Improvements in or relating to braking systems for vehicles
IPC: B60T11/16
Filed: 1936-07-17
Abstract: 478,328. Fluid-pressure brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, D. T. July 17, 1936, No. 19905. [Class 103 (i)] A vehicle braking system comprising a master cylinder unit having a main piston which is forced along the cylinder to create liquid pressure, an intermediate piston in said cylinder acted upon by said liquid pressure, and mechanical means adapted to connect operatively the main and intermediate pistons should the movement of the main piston fail to create liquid pressure, is characterized in that the liquid pressure normally created by the main piston is communicated to a wheel brake assembly by a pipeline, the intermediate piston being connected by a mechanical rigging with another wheel brake assembly, whereby the ratio between the brake-applying force transmitted through the pipe-line and that applied through the mechanical rigging by the action of the pressure liquid is maintained constant. A master cylinder 10 has a piston 13 defining a space 20 in communication with hydraulic wheel cylinders 22, 23. The piston has a stem 26 connected to a head 27 which has radial projections adapted to slide in slots 34 in a sleeve 30 which slides over the stem 26, carries a piston 31, and is connected at 36.. 39 to mechanically actuated brakes 40, 41. The pedal-actuated member 28 is adapted to act upon the head 27 to which an auxiliary piston 42 is secured. A reservoir 15 feeds liquid through a passage 17 to a space 18 behind the main piston 13, a small breathing aperture 19 being provided just in front of the lip of a packing cup 14 in the inoperative position of the piston. Packing cups are also provided at 32, 33, 43. Between the cups 32, 43 is an auxiliary working space 44 of variable volume in communication through a passage 45 with the main working space 20. In operation, movement of the arm 28 anticlockwise causes the pistons 13, 42 to move forward. This produces mechanical actuation of the brakes 40, 41 and creates pressure in the main cylinder 20 which is transmitted to the space 44. As the pressure builds up the wheel brake cylinders 22, 23 are also actuated, and a time arrives when the pressure in the space 44 is of such value that the piston 31 is moved away from the piston 42 thus applying the hydraulic pressure to the previously mechanically-actuated brakes 40, 41, the sleeve 30 then being separated from the head 27. In the event of a breakage or leakage in the hydraulic system, the arm 28 is still able to press on the head 27 to effect mechanical actuation of the brakes 40, 41.

Title: Improvements in and relating to electrothermally operated electric vacuum switches
IPC: H01H37/50
Filed: 1930-07-01
Abstract: 354,020. Thermal switches. SCHERBIUS & RITTER KOMMANDIT-GES., 40, Konigstrasse, Wannsee, Berlin. July 1, 1930, No. 19989. Convention date, July 1, 1929. [Class 38 (v).] Cases.-Wires or strips arranged in parallel mechanically (so that their pulling forces are added together) and in series electrically are arranged within a vessel which is evacuated or filled with inert gas and serve to operate contacts also located in the vessel. In the construction shown in Fig. 1, the wire is wound round two insulating rollers 8 each of which may be divided into a series of small rollers. The lower roller is secured to the contact member 1 which carries the contact 2 and the upper one is mounted for slight upward and downward movement in a frame 12 moving on a fixed pin 29. The companion contact 5 is carried by a spring arm 4 which bears upon the frame 12 and keeps the wire taut. The wire becomes heated when a current flows in it and expands so that the spring arm 4 is able to rise and withdraw its contact 5. When the circuit is broken the wire contacts and circuit is made again so that the device serves as a continuous interrupter. In a modified construction, the wire is wound in zig-zag form concentrically round two contacts which under the action of a spring separate when the wire expands due to the current carried by it. A tubular insulating arcbarrier may be arranged between the wires and the contacts. In another form, Fig. 3, the wires 19 are arranged in diamond form with the spring arms carrying the contacts 27, 28 serving to keep the wires taut. Alternatively the wire structure may act on a lever which, when the wires contract, raise the movable contact from the fixed contact.

Patent GB-803552-A (GB)
Title: Dehydration process
Filed: 1955-07-13
Abstract: In a process for the preparation of a mixture of reduced water content from a mixture of methylene chloride and a lower fatty alcohol, where sufficient water is present to cause separation into two phases, the aqueous phase is separated from the methylene chloride phase and an azeotrope of methylene chloride and water is distilled from the aqueous phase, and the methylene chloride distilled from the aqueous phase is combined with the methylene chloride phase.  The alcohol may be methanol, ethanol, isopropanol or n-propanol, and the methylene chloride may represent 80 to 99 per cent by weight of the methylene chloride and alcohol together. The distillate may be added to the methylene chloride phase, with or without first removing the aqueous phase obtained when the methylene chloride and water azeotrope is condensed.  The distillation may be continued to obtain a distillate consisting of the alcohol or an azeotrope of the alcohol and water, which may also be added to the methylene chloride phase.  The methylene chloride phase with the added distillate may be distilled to remove a methylene chloride-water azeotrope, which is condensed, and the methylene chloride phase returned to the distilland, the distillation being continued until the water content of the distilland is reduced to a desired level.  The methylene chloride phase obtained on condensing the distillate from the first aqueous phase, may be further distilled to remove water as a methylene chloride-water azeotrope, which is condensed and the methylene chloride returned to the distilland, distillation being continued until the water content is reduced to the desired level, the methylene chloride so-obtained being combined with the first methylene chloride phase.  Examples of the process are given.

Abstract: 432,241. Two-part couplings. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Garfield Manufacturing Co. ; Garfield, New Jersey, U.S.A.) July 11, 1934, No. 20356. [Class 38 (i)] A coupling comprises spring-pressed contacts that are deflected as the coupling-members are brought together and then released to make contact with the contacts on the counterpart under the action of the spring. Each contact 16 mounted in a recess 20 by means of a pin 22 and a pair of washers 21, 24 is held in its normal position by a spring 27. A T-shaped head 19 on the contact engages a pair of oblique guides 29 by which the spring 27 is compressed as the two coupling-members 2, 3 are brought together. When the members 2, 3 are fully engaged the head 19 passes beyond the edge 32 of the guides 29 and flies up into engagement with the contact 17. On separating the members 2, 3 the contact 16 flies up into the recess 34 to provide a quick break and prevent re-engagement of the contacts. When both make and break occur the part 13 of the member 2 is within the space 12 in the member 3, the contacts being thus cut off from the atmosphere. An earthing pin and socket 36, 37, which are connected by screws 38, 39 to the metal casings 4, 6 and by terminals 41, 42 to earth leads, come into engagement before the live contacts and form a guide which is located eccentrically.
